Dryer Takes Too Long
The part(s) or condition(s) listed below for the symptom Dryer takes too long are ordered from most likely to least likely to occur. Check or test each item, starting with the items at the top of the page.
If the vent is clogged or partially clogged, it will restrict the airflow through the dryer, substantially increasing the drying time. To ensure proper dryer performance, you should clean your dryer’s venting system at least once per year.
The blower wheel works with the drive motor to draw air into the dryer drum. Clumps of lint, socks, and small articles of clothing can escape the lint filter and get caught in the blower wheel. In addition, the blower wheel sleeve can wear out, allowing the blower wheel to wobble on the motor shaft. If the blower wheel is obstructed or defective, it may take too long to dry clothes. To determine if the blower wheel is working properly, remove the dryer vent and assess the strength of the air flow. If the air flow is weak, check the blower wheel for obstructions. If no obstructions are present, try rotating the blower wheel by hand. If the blower wheel wobbles as it turns, replace it.
Gas dryers have two or more gas valve solenoid coils. The gas valve solenoids open the gas valve to allow gas to flow into the burner assembly. Sometimes, a solenoid can fail several minutes into the drying cycle, causing the dryer to take a long time to dry the clothes. To determine if one or more of the gas valve solenoids has failed, check the igniter. If the igniter glows and goes out but does not ignite the gas, the gas valve solenoid is defective. If one or more of the gas valve coils are defective, we recommend that you replace them as a set.
The heating element warms the air before the air enters the dryer drum. If the heating element is burned out, or if any other part of the assembly is defective, the dryer may not heat. To determine if the heating element is at fault, use a multimeter to test it for continuity. If the heating element does not have continuity, replace it.
The lint filter might be clogged. Dryer sheets and fabric softener can leave a residue on the lint filter, reducing the air flow. If the lint filter is clogged, clean it.
The moisture sensor monitors the clothing’s moisture level and sends a signal to the control board when the clothes are dry. If the moisture sensor is malfunctioning, it could inaccurately report that the clothing is still moist, causing the dryer to keep running even though the clothes are dry. However, this is rarely the case. Before replacing the moisture sensor check all the more commonly defective parts. If you have determined that all of the other components are working properly, replace the moisture sensor.
The high-limit thermostat monitors the dryer temperature and shuts off the burner if the dryer overheats. If the high-limit thermostat is malfunctioning, it may shut off the burner even if the dryer is not overheating. However, this is rarely the case. Before replacing the high limit thermostat check all the more commonly defective parts. If you have determined that all of the other components are working properly, test the thermostat by using a multimeter to test it for continuity. If the thermostat does not have continuity, replace it.
The cycling thermostat cycles the heat on and off to regulate the air temperature. If the cycling thermostat is defective, the dryer will not heat. However, this is rarely the case. Before replacing the cycling thermostat check all the more commonly defective parts. If you have determined that all of the other components are working properly, test the thermostat by using a multimeter to test for continuity. If the thermostat does not have continuity, replace it.
Some dryer models have a thermistor. The control board uses the thermistor to monitor the dryer temperature and cycle the heat on and off. If the thermistor is defective, it might not cycle the heat on, causing the clothes to not to dry properly.
